Using GT/CAPP to Enhance Product Data Exchange Standard — Key to CAD/CAM Integration

The ability to exchange standard data among various computer-aided design (CAD) and computer-aided manufacturing (CAM) tools used in discrete parts manufacturing provides an important key with regard to the full implementation of computer-integrated manufacturing (CIM). This paper will discuss two coding techniques which will enhance the process of data transfer on two levels. This approach involves the creation of product codes which are used on the production planning level and feature codes which are used on the operational level. “C” language computer programs have been written to create an interactive procedure which places the designer in the manufacturing loop. The impact of group technology integrated with computer-aided process planning (GT/CAPP) on the generation of a product data exchange standard (PDES) will be demonstrated.
